New grades for turning operations With Double-BridgeӔ into a new dimension >

To meet the continuously growingdemands of modern tool concepts as to economic efficiency and productivity, Tungaloy designed the new T9000 series. The result of our intensive research and development is a modern cutting grade series, which stands for increased tool lifeat higher cutting speeds in machiningoperations of steel. Compared to traditio- nal cutting materials, the new MT-CVD coated substrate has a unique design of each single coating layer. The patented new Double-BridgeӔ coating technology stands for extremely increased adhesion of each single layer. Thus thicker coatings can be applied...
